The Holy Family consists of the Child Jesus, the Virgin Mary, and Saint Joseph. Veneration of the Holy Family was formally begun in the 17th century by Saint François de Laval, the first bishop of New France, who founded a Confraternity. The Feast of the Holy Family is a liturgical celebration in the Catholic Church and some Anglican Churches in honor of Jesus, his mother, and his legal father, Saint Joseph, as a family. The primary purpose of this feast is to present the Holy Family as a model for Christian families. The Feast is held on the Sunday between Christmas and New Year's Day; If both are Sundays, the feast is celebrated on December 30th.
Background
The Gospels speak little of the life of the Holy Family in the years before Jesus’ public ministry. Matthew and Luke narrate the episodes from this period of Christ's life, namely his circumcision and later Presentation, the flight to Egypt, the return to Nazareth, and the Finding in the Temple. Joseph and Mary were apparently observant Jews, as Luke narrates that they brought Jesus with them on the annual pilgrimage to Jerusalem with other Jewish families.
Veneration
The Feast of the Holy Family is a liturgical celebration in the Catholic Church in honor of Jesus of Nazareth, his mother, the Blessed Virgin Mary, and his foster father, Saint Joseph, as a family. The primary purpose of this feast is to present the Holy Family as a model for Christian families. From the 17th century, the feast has been celebrated at a local and regional level and at that level was promoted by Pope Leo XIII. In 1921, Pope Benedict XV made it part of the General Roman Calendar and set on the Sunday within the Octave of the Epiphany; that is to say, on the Sunday between January 7 through January 13, all inclusive. The 1962 Roman Missal, whose use is still authorized in the circumstances indicated in the 2007 motu proprioSummorum Pontificum, follows the General Roman Calendar of 1960, which has the celebration on that date. The 1969 revision of the General Roman Calendar moved the celebration to Christmastide, assigning it to the Sunday within the Octave of Christmas, that is, the Sunday between Christmas Day and New Year's Day, or if both Christmas Day and the Solemnity of Mary, Mother of God are Sundays, on 30 December. When not celebrated on a Sunday, it is not a holy day of obligation. Formerly, the Sunday within the Octave of Christmas was in fact celebrated only if it fell on 29, 30 or 31 December, since it gave way to the higher ranked feasts of Saint Stephen, Saint John the Apostle and the Holy Innocents. The Feast of the Holy Family that has replaced it outranks these three feasts.
